目的探讨韦尼克脑病(Wernicke’s encephalopathy,WE)的病因、发病机制、临床表现及治疗,提高对韦尼克脑病的认识和早期临床诊断率,减少临床误诊率。方法对济宁医学院附属医院肾内科、消化科、产科、神经内科、胃肠外科2005-01—2015-12收治的20例(男12例,女8例,年龄21~72岁)WE患者的病史、临床特征、诊断、治疗以及预后进行分析。结果饮酒为韦尼克脑病最常见的病因,临床表现多种多样,典型的临床表现为眼球运动麻痹、共济失调和意识精神障碍三大主征,但典型的WE"三联征"很少同时出现,20例患者中只有2例(10%)表现为典型的三联征。绝大多数患者经大剂量补充维生素B_1后疗效显著。结论 WE病因及临床表现复杂多样,早期诊断十分困难,颅脑MRI可作为诊断此病的重要辅助检查。及时大量补充维生素B_1可以明显改善患者预后情况。 相似文献

目的探讨韦尼克脑病(Wernicke’s encephalopathy,WE)的病因、临床表现、磁共振特征、误诊原因和治疗转归。方法回顾性分析我院2012年10月~2015年6月收治的35例WE患者的临床资料。结果饮酒是WE最常见原因,其次是胃、胆囊、胰腺病变导致呕吐和进食差。具有典型的精神意识障碍、眼肌麻痹、共济失调三联征者占11.4%,具备三联征中两项者占42.9%,仅有三联征中一项者占45.7%。头部MRI可见双侧丘脑、侧脑室周围、导水管周围、第三脑室、四脑室旁、乳头体、皮质、胼胝体等部位对称性异常信号。本组患者的误诊率达60%,其中酒精中毒性WE误诊率为54.17%,非酒精中毒性WE误诊率为72.73%。住院期间91.42%患者(32/35)好转,8.58%患者无好转。出院5 m时9例失访,随访的26例中6例死亡(死亡率23.07%),13例痊愈(50%),5例遗留记忆力障碍,2例完全卧床。结论 WE病因及临床表现多样,MRI有特征性改变,但早期误诊率高,预后与是否诊断和治疗及时密切相关。 相似文献

目的非酒精性韦尼克脑病(Wernicke encehalopathy,WE)易误诊,本文旨在提高对该病的认识。方法回顾性分析6例非酒精性WE患者临床及MRI特征。结果 6例患者均出现不同程度的意识障碍,其中仅2例表现为经典的三联征。6例患者均出现双侧对称性丘脑内侧、脑室及导水管周围、中脑顶盖异常信号典型表现,同时2例深昏迷患者分别表现出弥漫性皮层及面神经核受累。随访患者平均恢复时间为7.5个月,而MRI则为2.8个月。2例深昏迷患者预后较差,1例患者死亡,另1例2年后仍遗留严重四肢痉挛性瘫痪,并伴智能低下。2例深昏迷患者DWI上表现为广泛高信号。结论 MRI可为非酒精性WE提供早期诊断,而病变累及广泛皮层及颅神经核可能提示较差的预后,同时DWI序列可能有一定的预后作用。 相似文献

目的 分析非乙醇中毒性韦尼克脑病(WE)患者的临床和颅脑MRI成像特点,探讨颅脑MRI对其的诊断价值. 方法 深圳市第二人民医院放射科自2007年6月至2010年2月应用MRI检查非乙醇中毒性WE患者5例,回顾性分析患者的临床特征、颅脑MRI成像特点及治疗转归等资料. 结果 非乙醇中毒性WE患者缺乏特征性临床表现,颅脑MRI主要表现为丘脑内侧,侧脑室,第三脑室,中脑导水管周围脑组织对称性高信号,2例患者可见大脑皮层受累.增强扫描后部分病变可见强化.2例患者死亡,3例患者应用维生素B1治疗后预后良好. 结论 颅脑MRI对非乙醇中毒性WE具有诊断价值,其显示的损害范围可反映WE的疾病严重程度.Abstract: Objective To analyze the clinical features and MR imaging features of patients with nonalcoholic Wemicke's encephalopathy (WE). Methods A retrospective review of the data,consisting of clinical and cranial MRI features, and the treatment results, was conducted on 5 patients with nonalcoholic WE, who admitted to our hospital fiom June 2007 to February 2010. Results The clinical features of nonalcoholic WE were non-characterized and most of them had no specific value for diagnosis. MR imaging showed symmetrical high signal in the medial thalamus, lateral ventricle, third ventricle and surrounding area of the aqueduct of midbrain; involvement of the cerebral cortex was found in 2 patients. Enhancement in some of the lesions was noted after performing contrast-enhanced scan.Favorable prognosis was given to the 3 patients treated with vitamin B1; 2 patients died. Conclusion Cerebral MRI enjoys great value in diagnosing nonalcoholic WE and reflects appropriately the pathological severity of this disease by demonstrating the scope of the lesions. 相似文献

A report is presented on a patient with Wernicke's encephalopathy secondary to hyperemesis gravidarum. The 25-year-old female presented 11 weeks into pregnancy with prolonged vomiting. Neurological examination 8 weeks later demonstrated obtunded sensations, nystagmus and ataxia of gait. MR imaging revealed bilateral lesions in the mediodorsal nuclei of thalami, in the hypothalamus and in the periaqueductal gray matter (1). The neurological signs and the MRI findings pointed to a diagnosis of Wernicke's encephalopathy. The patient was treated with intramuscular vitamin B1 followed by oral thiamine until the end of pregnancy. The subsequent course of the pregnancy was uncomplicated, and resulted in the delivery of a healthy 2970 g male infant. A review of the literature published during the last 30 years revealed an additional 20 cases of Wernicke's encephalopathy induced by hyperemesis gravidarum. Only half of these pregnancies resulted in the birth of a normal infant. 相似文献

The nature and distribution of vascular changes in acute Wernicke's encephalopathy (WE) were analyzed in three autopsy cases. Lesions of the lateral vestibular nucleus of the medulla oblongata (three cases) and lateral ventricular wall (one case) were examined by reconstruction of 200 serial sections, and the capillary diameter in the tegmentum of the medulla oblongata was measured morphometrically in all cases. The vascular changes commonly found in and around the parenchymal lesions in all cases were: (1) dilatation and endothelial swelling of almost all vessels ranging from small arteries to veins, being especially severe with undulation in small arteries and arterioles, and (2) fibrinoid degeneration and hemorrhage involving selectively the arterioles and capillaries on the arterial side. These vascular changes in the medulla oblongata were essentially the same as those in the third ventricular wall, but differed in their severity. Capillary diameter in these cases was significantly larger than that in seven control cases. Such vascular changes, especially a dysoric change on the arterial side, could not be ascribed to secondary change following changes in the parenchyma, and were, therefore, considered to be a lesion essential to WE, as in the case of the parenchymal lesion. 相似文献

OBJECTIVE: To report diffusion-weighted imaging (DWI) findings and postulate the pathogenic mechanism of Wernicke's encephalopathy (WE). PATIENT: A 47-year-old-woman presented with altered consciousness, ophthalmoplegia, and ataxia. DWI revealed the abnormal signal changes in periaqueductal gray matter, mamillary bodies and bilateral medial thalami. Apparent diffusion coefficient (ADC) map revealed the high signal intensity lesions in bilateral medial thalami, suggestive of vasogenic edema. The abnormal signal intensity lesions disappeared on follow-up imaging with clinical improvement. CONCLUSIONS: Vasogenic edema plays an important role in the pathogenesis of WE and can be reversed by proper management. DWI findings in the early stage of WE may provide useful information about the prognosis. 相似文献
